To all whom it may concern:

Be it .known that 1,:SVEN J ULIUs STRID,

a citizen of the'United States of America,

residing at Chicago, inthe eountyof Cook and .State of Illinois, United States of America, have invented .a new and vuseful lm-provementina Draft Gear, of which the following i'sa full, clear, and. exact description,-such. as -.wi1l :enable "others 1 skilled in the art to make and use the same.

invention relates to-draft gear for railway. cars. -.and :has more particular refierence to theconstru'ction andarrangement of .thewback: stop blocksand theside lugs against-whiclrthe draw-bar yoke bears.

Heret-ofore, in the construction ofrailway car underframes, it .has been the practice 1' to provide. a. center-sill formed of-a plurality of angle beams, and the transverse':-body-b0lster, which is over the trucks, has beeninniany instances formed with side; pieces extending-transversely from the center-sill to the respective; side-sills of the car and :there' is-an intermediate center-filler casting placed between the center-sill. members. in alinement with thetransverse bodybolster members. In numerous approved draft gear arrangements, the back stop for the draw-bar yoke has beenmade either as .apart. of or separate from. and abutting against .the center-filler casting. -As the body-bolster, including this center-filler casting,-is under tremendous vertical stress in supporting the car super-structure as well asthe. load stress when the car is loaded, I findrthat theeaforesaid arrangement of the back-stop with respect to the center-filler casting; is objectionable because of the additional. burden placed upon this casting due to therlongitudinal or .horizontalthrust oc-, casioned bythe=push and pull upon the draft gear.

-I have, therefore, designated a constructionin which the thrust upon the back-stop is :neitherreceived nor absorbed by. the: center--filler casting, butthis stress .is passed through the body-bolster center-filler to a.

the center-sill wherethe elfect of the thrust on the draft gear is not felt by the bodybolster-and its center-filler casting. The ob jects of my present invention are to provide a structure as last suggested, which is simple in construction, novel in the arrangementof its parts, is compact, andiis *dependable ae.

well as durable in operation. n

l prefer to carryout my nvention and to accomplish the divers objects thereof in substantially the manner hereinafter fully dc-1 scribed andas more particularly pointedout.

in the claims, reference being .here made? to the accompanying drawings forming. apart of this specification.

In the drawings:

The drawings illustrate in schematic form a typical or preferredembodiment of my invention and slight modifications there-t of a. portion of ence characters to designate like parts .wherever they appear throughout the several views. v J

Referring first to Figures 1, '2 and. 8, it will :be seen the center-sill comprises .two channel beams .10, 10, that are spacedapart longitudinally, with their flanges. projecting away from each other and with theirw'ebs vertically disposechwin the usual manner'rof under-frame construction. The body bol.- ster consists -of oppositely extending members-or castings 11, 11, .thatare secured, to the respective webs of the channels. comprising the center-sill, and saidlmembers extend transversely out. from the center-sill .tof'lthe sides-of the car. For the purpose of re inforcement and toprovide continuous composite body-bolster there is a center-filler casting 12 mterposed between :and fillingflthe space between the center-sill channel-beams 10 and in longitudinal alineinent with the opposite members 11 of the body-bolster and a tie plate 13 connects the assembled parts in the usual manner. The yoke l l is positioned longitudinally between the centersill channels 10 forward of the center-filler casting and extends to ards the end of the car, where it is connected to the drawar, the coupler-jaws, or other appliance. As before stated, it has been the practice to abut the draw-bar yoke against a rack-stop that is formed as a part-or or is connected to the center-filler block of the body-bolster. With my present invention I provide backstops or side-lugs upon the other side of the center-filler casting from the draw-bar yoke and place blocks or extensions through the center-filler casting to engage with the rear or inner end of the draw-bar yoke.

The center-filler casting which is of hollow construction is provided centrally with a tubular embossment 15 to receive the kingbolt 16, and in order to carry out my invention the casting is provided with horizontally-disposed shelves or supporting straps 17 and 18. Above these straps and alining respectively therewith are retaining straps 19 and 20. These sets of straps at the forward and rear ends of the center-filler casting provide guides and supports for the blocks or extensions 21, which are arranged in pairs, one upon each side of the kingbolt. As seen in Figure 1, these blocks are reduced slightly in width so as to extend past the king-bolt einbossinent 15 and the ends of these blocks project beyond the respective ends of the center-filler casting so that at their forward ends they abut the rear or inner transverse end of the draw-bar yoke 141-. The opposite ends of these blocks 21, in the form shown in Figures 1, 2, 8 and 6, abut the transverse webs 22 ofthe backstops 0r side-lugs 23 that are secured to the channeled members of the center-sill. These back-stops or side-lugs may be of any desired construction and are preferably re-inforced by gusset walls, as seen in the drawings. In order to prevent the accidental dislodginent of the blocks 21 in a longitudinal direction, stop-pins 241 are removably placed in the upper portion of the blocks, so as to engage with the adjacent retaining strap 19.

In the modification illustrated in Figure 6, the stop-pins 24 have been dispensed with and the blocks 21 are widened intermediate their ends as at 25 and are provided efiect of the same is felt by the body-bolster beyond its center-filler casting, and damage to said bolster or center-filler casting, such as the shearing of the rivets or the twisting of the center-filler casting is avoided. It will also be seen that I have provided an extremely simple xpediency for carrying out my invention and it will be obvious that modifications other than those herein shown and described may be made without departing from the principles involved, and I desire it understood that all such modifications and refinements are contemplated as coming fully within the scope of my invention as expressed in the appended claims.

lVhat I claim is 1. In a structure of the kind described a center-sill, a body-bolster disposed trans verse thereto including a center filler casting, a draw-bar yoke positioned upon one side of said casting, aback-stop therefor upon the opposite side of said casting and connected to said center-sill, and means extending from said back-stop to said drawbar yoke whereby the thrust from the latter is transmitted through said stop to the center-sill independently of the center filler casting.

2. In a structure of the kind describedthe center sill, a body-bolster extending transverse thereto including a center filler casting, a draw-bar yoke upon one side of said casting, a back-stop connected to said center-sill upon the opposite side of said casting, and a block extending from said stop through said center filler casting to said yoke whereby the thrust of the latter is transmitted to the center-sill independently of the center fillercasting.

3. In a railway draft-gear a back-stop structure consisting of a plate secured to the center-sill of the car and having a member projecting laterally therefrom, and a device extending from said lateral member through the body-bolster towards the adjacent end of the car. I

l. In a railway draft-gear a back-stop structure consisting of a plate secured to the center-sill of the car, and an elongated block extending centrally through and un secured to the body-bolster for engagement with the draw-bar yoke, said plate having a stop lug adjacent the body-bolster engaged by the opposite end of said block.

5. A structure of the kind described comprising a center-sill, a body-bolster formed of alining side members positioned transversely of the center-sill and a center filler casting interposed between said side members, said casting and side member secured to said center-sill, a back-stop secured to the center-sill adjacent to and independent of the center fillercasting, and an elongated block extending through said casting into engagement at one end with said back-stop and adapted at its opposite end to be engaged by the draw-bar yoke.

6. A structure of the kind described comprising a center-sill, a body bolster secured transversely thereto, a draw-bar yoke within said sill upon one side of said bolster, and a back-stop for said yoke secured to said sill and provided with means whereby the longitudinal thrust of said yoke is transmitted to the back-stop and sill independently of said bolster.

7. A structure of the kind described comprising a center-sill and a body-bolster therefor, in combination with a draw-bar yoke and a back-stop for the latter positioned respectively upon opposite sides of said bolster, and a member extending through said bolster and unsecured thereto said member at opposite ends engaged respectively by said yoke and said back-stop.

8. A structure of the kind described comprising a center-sill and a body-bolster therefor, in combination with a draw-bar yoke and a back-stop for the latter positioned respectively upon opposite sides of said bolster, and a block supported by a part of said bolster and extended therethrough whereby to engage at its opposite ends respectively with said yoke and back-stop and thereby transmit the thrust of the former to the latter independently of the body-bolster.
